IFXPVT422PBF

Overview

The PVT422PBF is a dual-pole, normally open (2 Form A) solid-state relay designed for switching AC and DC loads up to 400V. It utilizes Infineon's HEXFET power MOSFET technology as the output switch, driven by a specialized integrated circuit and an AlGaAs light-emitting diode. This photovoltaic relay provides high input-to-output isolation and is housed in an 8-pin DIP package.

Why Choose This Part

This relay offers a significantly longer operational life than electromechanical relays by eliminating contact bounce and mechanical wear. It features a very low LED operate current of 3mA maximum and provides dual-channel switching in a compact 8-pin footprint. The device is rated for a wide operating temperature range from -40C to +85C, making it suitable for harsh industrial settings.

Applications

Getting Started

When designing with the PVT422PBF, ensure the input LED current is limited by a series resistor to meet the 3mA maximum operate threshold. Designers should provide adequate clearance for the 400V load side traces on the PCB to maintain isolation safety. No external snubber circuits are typically required for inductive loads, but thermal derating should be considered if switching the full 160mA continuous load at high ambient temperatures.
